Amazing looking game, well implemented and crazy how much the main idea resembles a jam game I submitted last week (Bob's Building Bonanza if you're interested. A platformer where you also have to build your way through the level).
The auto moving makes this one very challenging. Timing the jumps to go up the big ladder without painting was very satisfying. The danger stuff is a bit too much for me. 3 of them so close to eachother with a fast moving character means you need to be able to react very fast, and I have enough trouble already just getting my butterfly where I want him to go.
Very well put together (and a bit of a spoiler: The highest number of stars I gave out this jam so far :P)
